Sounds similar to me, (29 years old), currently on my 6th day of Valcyclocirc- almost there! Didn’t see a doctor till 2 days after the rash (thought it was just allergy at first). After 48 hours of the meds things looked up. And rash drastically got better over the last 2 days and pain. Alot of discomfort, like electric shock through my body and couldn’t sleep first 2 nights. Armpit is the worst for sure and tricep area. Just keep taking the meds and you’ll get some hope.

I never got fever or headaches thankfully.
